XSLT pass array of Integers

Hos do I pass array of Integers as a params to XSLT?.

From stackoverflow

• You can pass it in an xml format. That would make processing in the xslt easier too.

  <array>
   <int>23</int>
   <int>45</int>
  </array>
  

  You can then process it in your xslt as:

  <xsl:param name="intArray" />
  ...
  ...
  <xsl:template match="/">
   ...
   <xsl:for-each select="$intArray/int">
    <!-- Process int array -->
    ...
    ...
   </xsl:for-each>
  </xsl:template>
  

• Convert it into comma-separated string
